Quantum transport in topological semimetals under magnetic fields

HZ Lu, SQ Shen - Frontiers of Physics, 2017 - Springer
Topological semimetals are three-dimensional topological states of matter, in which the
conduction and valence bands touch at a finite number of points, ie, the Weyl nodes …

Negative magnetoresistance in Dirac semimetal Cd3As2

H Li, H He, HZ Lu, H Zhang, H Liu, R Ma, Z Fan… - Nature …, 2016 - nature.com
A large negative magnetoresistance (NMR) is anticipated in topological semimetals in
parallel magnetic fields, demonstrating the chiral anomaly, a long-sought high-energy …

Magnetotransport in a model of a disordered strange metal

AA Patel, J McGreevy, DP Arovas, S Sachdev - Physical Review X, 2018 - APS
Despite much theoretical effort, there is no complete theory of the “strange” metal state of the
high temperature superconductors, and its linear-in-temperature T resistivity. Recent …

Magnetotransport phenomena related to the chiral anomaly in Weyl semimetals

BZ Spivak, AV Andreev - Physical Review B, 2016 - APS
We present a theory of magnetotransport phenomena related to the chiral anomaly in Weyl
semimetals. We show that conductivity, thermal conductivity, thermoelectric, and the sound …

Magnetoresistance and valley degree of freedom in bulk bismuth

Z Zhu, B Fauqué, K Behnia… - Journal of Physics …, 2018 - iopscience.iop.org
In this paper, we first review fundamental aspects of magnetoresistance in multi-valley
systems based on the semiclassical theory. Then we will review experimental evidence and …

Linear magnetoconductivity in an intrinsic topological Weyl semimetal

SB Zhang, HZ Lu, SQ Shen - New Journal of Physics, 2016 - iopscience.iop.org
Searching for the signature of the violation of chiral charge conservation in solids has
inspired a growing passion for the magneto-transport in topological semimetals. One of the …

Topological states on fractal lattices

S Pai, A Prem - Physical Review B, 2019 - APS
We investigate the fate of topological states on fractal lattices. Focusing on a spinless chiral
p-wave paired superconductor, we find that this model supports two qualitatively distinct …

Metamagnetic multiband Hall effect in Ising antiferromagnet ErGa2

T Kurumaji, S Fang, L Ye, S Kitou… - Proceedings of the …, 2024 - National Acad Sciences
Frustrated rare-earth-based intermetallics provide a promising platform for emergent
magnetotransport properties through exchange coupling between conduction electrons and …

Anomalous conductivity tensor in the Dirac semimetal Na3Bi

J Xiong, S Kushwaha, J Krizan, T Liang… - Europhysics …, 2016 - iopscience.iop.org
Abstract Na 3 Bi is a Dirac semimetal with protected nodes that may be sensitive to the
breaking of time-reversal invariance in a magnetic field B. We report experiments which …

Aperiodic weak topological superconductors

IC Fulga, DI Pikulin, TA Loring - Physical review letters, 2016 - APS
Weak topological phases are usually described in terms of protection by the lattice
translation symmetry. Their characterization explicitly relies on periodicity since weak …
